Multi-Party Protocols are methods used in computer science and cryptography that allow multiple parties to jointly compute a function while keeping their individual inputs private. These protocols ensure that no single party can access the complete data of others, promoting privacy and security in collaborative computations. These protocols are essential in various applications, such as secure voting systems, blockchain technologies, and secure multi-party computation (SMPC). By enabling trust among participants, Multi-Party Protocols facilitate cooperation in scenarios where data sensitivity is crucial, ensuring that all parties can contribute without compromising their private information.
